Both depends on a filesystem organization rework.

Would it be useful to have the syntax support in 9.1 already, but which
would only check that the asked-of new version (and current version) are
the one currently available (and installed), and ERROR out otherwise?
I think that syntax-and-check is still doable for 9.1, if there's a will
to get there.
